Packaging EPR Data Mistakes Costing Producers Thousands

July 21st, 2026

Packaging EPR data mistakes are costing UK producers more than they realise. Incorrect packaging weights, material classifications and reporting errors can increase compliance fees, trigger resubmissions and expose businesses to regulatory scrutiny. As 2026 reporting obligations continue, accurate Packaging EPR data is no longer just a compliance requirement, it's essential for controlling costs and reducing risk.

Why Packaging EPR Data Accuracy Directly Impacts Your Costs

Extended Producer Responsibility is reshaping how UK businesses account for the packaging they place on the market. The fees producers pay are calculated from the data they submit. That means packaging EPR data mistakes risk both a compliance penalty and directly inflating your costs.

Businesses across every sector, from retail to manufacturing, food and drink and logistics, are all affected. And while most producers are genuinely trying to comply, many are unknowingly submitting data that contains costly errors. Understanding where those mistakes happen is the first step to fixing them.

The scale of data errors in the first year of packaging EPR was significant enough to destabilise the system and prompt government intervention. The message is clear: data errors have a direct and measurable effect on what producers pay and the stability of the new packaging EPR system.

If you're responsible for pEPR compliance, you already know your submission is only as good as the data behind it. If you have poor data and get the numbers wrong, you'll either overpay or underpay, or worse, end up explaining your poor data to the Regulator.

Inaccurate or incomplete data carries consequences;

Financial penalties for missed deadlines
Civil sanctions and enforcement action for not registering or knowingly submitting incomplete data
Overpayments when material weights are calculated too generously
Reputational damage as transparency expectations rise from customers, investors and regulators

Tracey Joyce, Data Services Delivery Manager at ERP UK says: "We see producers at all stages of EPR maturity making the same core mistakes. Often there is a lack of the right framework for capturing data consistently across their supply chain. Once that framework is in place, the data quality improves significantly and the financial picture becomes much clearer."

Why Packaging EPR Data Mistakes Continue to Cost Producers Money

As Tracey has noted, most packaging EPR data mistakes come from structural problems in how data is collected in the first place. Three root causes appear repeatedly across producers of all sizes.

A piecemeal, reactive approach. Many producers only address data gaps when they are discovered, often by chance, and often close to a submission deadline. This leads to inconsistencies, duplication and misclassification. The more effective approach is to capture data much earlier – ideally at the point when packaging is handled, supplied, shipped, manufactured or imported. Treating data collection as an ongoing process, rather than a pre-deadline scramble, removes the conditions that allow errors to build up.

Not knowing your data source. Companies frequently fail to verify where their data originates, which makes it impossible to confirm accuracy. Before relying on any data, producers should ask: is this source trustworthy? When was it last checked? How was it captured? Is anything missing? Packaging and material specification sheets can be valid sources that can fill gaps where data is unavailable.

Inconsistent data formats. Free-text entry and mixed units create unreliable data that is difficult to validate or audit. Using structured, fixed-field forms with pre-selected options and required fields enforces consistency. Fixed fields for weight (kg or g only), pre-selection for material and packaging types, and metadata capture (who submitted the data, when and how) all reduce the risk of format-driven errors.

Addressing these three root causes doesn't require a complete overhaul of your compliance process. But it does require a deliberate, systematic approach, one that considers every compliance obligation upfront rather than patching gaps as they appear.

7 Packaging EPR Data Mistakes That Increase Compliance Costs

Packaging EPR requires producers to capture, categorise and report data across their entire supply chain. That means tracking every material type, every packaging format and every nation where products are sold. For businesses with multiple product lines, third-party logistics or complex supply chains, the margin for error is significant.

The most common packaging EPR data mistakes include:

Misclassifying materials — confusing plastic film with rigid plastic, or mislabelling composite materials, leads to incorrect fee calculations and potential under-reporting. Producers must record material values in kilograms to at least two decimal places, differentiating exact materials such as cardboard, PET or steel.
Using estimates and averages — relying on estimated weights rather than physical weighing is a named compliance error. The correct approach is to weigh each component individually, ideally in grams, rather than guessing totals. Estimates introduce inaccuracies that compound across large volumes or product ranges.
Double reporting — this occurs when the same packaging is reported by more than one party, for example an overseas manufacturer and the UK importer both reporting the same packaging. Only the first UK entity to handle the packaged goods is legally the "producer". Reporting the same packaging across different activities inflates obligations and therefore costs and creates discrepancies that are difficult to unpick under scrutiny.
Ignoring supplier updates — using legacy or outdated data instead of checking for recent changes made by suppliers is a distinct and costly mistake. Suppliers regularly make lightweighting adjustments or material substitutions. If your data doesn't reflect those changes, your submissions won't either.
Inconsistent units — mixing kilograms and tonnes, or applying different rounding conventions across data sets, creates discrepancies that compound over time.

Missing supplier evidence — without documented evidence from suppliers on packaging weights and materials, data becomes unverifiable and difficult to defend under scrutiny.
Gaps in packaging category breakdown — failing to correctly distinguish between primary, secondary, shipment and transit packaging means obligations are either over- or under-stated and will likely result in subsequent resubmissions

Packaging EPR Data Requirements: What Producers Must Capture

One of the most practical ways to reduce packaging EPR data mistakes is to know exactly what fields are required for every component you report. For each packaging item, producers need to capture:

Activity — how the packaging was placed on the market (sold, imported, hired, etc.)
Material and weight — the specific material (aluminium, glass, plastic, etc.) and weight in kg or g
Class — the functional role of the packaging (primary, secondary, shipment or transit)
Type — the waste stream it enters (household, non-household, street bin or drinks container)
Nation of sale — required where turnover exceeds £1 million and packaging exceeds 25 tonnes
Recyclability — from 2025, this includes components, polymer types and colour under the RAM methodology

Gaps in any of these fields create incomplete submissions. Identifying which fields are missing, by supplier, product or SKU, is a useful first step in any data review. Spreadsheets make this harder than it needs to be. Systems that track access, edits and sharing give you a much clearer audit trail and make anomalies easier to spot.

Regulators Are Increasing Scrutiny of Packaging EPR Data

The shift to producer-funded EPR has brought packaging data into sharp focus for regulators. The Environment Agency and its equivalents in each nation are increasingly scrutinising the accuracy of submissions, not just their existence. Full data traceability is now expected, and detailed collection guidance isavailable via the official UK Government Packaging Data Guidance. Businesses that previously relied on estimates or broad assumptions are finding those approaches no longer adequate.

Nation-of-sale reporting is a particular area of concern. Most producers sell into multiple UK nations through a mix of direct channels and third-party retailers, making it genuinely difficult to attribute packaging accurately. Yet the consequences of getting this wrong, even unintentionally, can be significant, reputationally.

How Better Packaging EPR Data Can Reduce Compliance Costs

There's a tendency to view EPR data management as a cost of doing business; a reporting burden that sits alongside everything else on the compliance team's desk. But the businesses getting this right are finding something different.

When packaging data is captured consistently and accurately, it creates a cleaner picture of your entire supply chain. You can see where packaging weight is concentrated, where material substitutions might reduce your fee liability and where supplier relationships need to be tightened up.

Compliance shouldn't be a reactive scramble at reporting deadlines. It should be a structured, data-driven process that gives producers confidence in their numbers and control over their costs. The businesses that treat EPR data as a strategic asset are the ones best placed to manage their obligations efficiently as the regulatory landscape continues to evolve.
